pomodoro: Overhaul block

[bim9262]

Changes:

• Set block state based on pomodoro state
• Set icon based on pomodoro state
• Allow pomodos to be counted with arabic numeral or tally marks Pomodoro: Alternative number format: arabic / decimal #2003

The previous config will still be valid with the current config since there are new formats for the various states.

Ideally this will be merged after the format duration is added so that we don't have an additional inflection point in the config.

With #2032 we won't need to expose two values for the current pomodoro number.

Hey, is there any update on this PR? I wanted to the timers to the configuration, but saw that a PR was already in place.

Once #2032 is merged we can review this change @aadilshabier

@MaxVerevkin are we ready to merge this?

Since we are introducing separate *_format options, maybe we can replace format + message + break_message with pomodoro_over_format and break_over_format (names are just examples)?

[bim9262]

format is used when there aren't any pomodoros are active, there's a prompt, or a pomodoro/break over message is being displaced.

I think we need to keep format, but message/break_message could be replaced with new formats for those states.

Although by adding removing the message/break_message, we don't have anything to send to notify_cmd
